The red phosphor YAl3(BO3)4∶Eu3+ was prepared successfully by chemical precipitation method.The phosphor was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and luminescence spectra.Using urea as precipitating agent,the single phase phosphor YAl3(BO3)4∶Eu3+ was obtained at 900 ℃ by calcining precipitation precursor,which is 300 ℃ lower than temperature of solid state reaction.The particles are approximately 300 nm size with narrow distribution range.The luminescent properties of YA...
